The length of a rectangle is 7 more than three times the width. the perimeter is 94 inches. find the length and width
.
Let w = width
then from "length of a rectangle is 7 more than three times the width":
3w+7 = length
.
2(w + 3w+7) = 94
2(4w+7) = 94
4w+7 = 47
4w = 40
w = 10 inches (width)
.
Length:
3w+7 = 3(10)+7 = 30+7 = 37 inches
